The MB082SP made of metal and has a matte black finish, eloquently made to protect your SSDs or hard drives, while allowing one to use it in most PC cases. The screw placement is on both the sides and bottom of the bracket, which are of the exact locations of a 3.5” hard drive. The tool-less drive installation creates a simple way to install your SSD/HDD. Once that is done, then install as you would normally do with a 3.5” hard drive. All that is needed is to slide the SSDs or hard drives in and the drives will automatically lock into place and secured by an EZ-Lock mechanism. The EZ-Lock works just like the way you install a battery in a compact digital camera. The EZ-Lock design not only benefits when you first install a drive, but also when you need to replace a failed SSD or hard drive. Unlike other brand’s bracket, you are no longer forced to deal with 12 small tiny screws, with the EZ-Lock system, simply toggle the EZ-Lock, pop up the drive and replace the failed drive in no time. This is perfect for a system that uses RAID. To reduce the amount of vibration in the drives and the case the MB082SP has a built in unique anti-vibration technology for each bay of the device.
